SCADA information for water networks planning - GeoSmartCity-CIP/gsc GitHub Wiki

This page describes the new software developed to allow water networks planning using the SCADA information as source of SOS sensors. A new 52°North SOS extension is developed to achieve this capability.

Description

Development of the 52°North SOS Wonderware Modeling Extension This is hosted in the repository of the 52°North Sensor Observation Service (SOS).

See: https://github.com/52North/SOS/pull/404

Branch: https://github.com/52North/SOS/tree/feature/dynamic_observable_objects

This 52°North SOS extension integrates SCADA - (Supervisory Control and Data Acquisition) models of Wonderware platforms in the 52°North Sensor Observation Service (SOS) adding their entities as "virtual" SOS objects (Offerings, Procedures, FOIs, Observations and so on).

The plugin queries the data registered in the SCADA database to inject them to output WEB responses. The data (Sensors, and historic-live records) are dynamically inserted using a mechanism of virtual injection of data in order to avoid to save them in the main database managed by the 52°North SOS service.

All SCADA entities configured, with their respective historic-live records, will create on-the-fly a set of available -Offering/Procedure/FeatureOfInterest/Observation/Timeseries- objects.

The plugin is configured using a settings file hosted in WEB-INF\dynamic-models folder. Each entry in this file defines the properties of a sensor type (with its database connection and its related geographical store).

We can define an entry for an SCADA/Wonderware object type similar to:

<model class="org.n52.sos.extensions.wonderware.SimpleFeatureModel">
  <name>SCADA_flowmeters</name>
  <description>My flowmeters.</description>
  <databaseDriverClass>com.microsoft.sqlserver.jdbc.SQLServerDriver</databaseDriverClass>
  <databaseConnectionUrl>jdbc:sqlserver://xxx.xxx.xxx.xxx:1433;DatabaseName=MyDatabase;user=myuser;Password=mypwd
  </databaseConnectionUrl>
  <featureStoreUrl>wonderware/Caudalimetros_SCADA.shp</featureStoreUrl>
  <featureKey>SCADA</featureKey>
  <attributes>
    <attribute>
      <attributeName>flow</attributeName>
      <fieldId>SCADA</fieldId>
      <dateFrom>2011-06-01 00:00:00</dateFrom>

      <stepTime>300000</stepTime>
      <RetrievalMode>Cyclic</RetrievalMode>
      <RetrievalAlignment>StartDateAligned</RetrievalAlignment>
    </attribute>
  </attributes>      
</model>

Where: * class: Java class used to manage a specific SCADA/Wonderware object. * name: Name of the object type (Unique). * description: Label or description. * databaseDriverClass: JDBC driver class to access to the database. * databaseConnectionUrl: Connection string to the database. * featureStoreUrl: Connection string to the GIS Feature Store. This store contains the related geometries of objects managed. * featureKey: Fieldname key of the features. * attributes: Settings set to configure the specific SCADA data retrieval mode.

Now, only shapefiles are supported as feature sources.

Branches

The 52°North SOS is a reference implementation of the OGC Sensor Observation Service specification (version 2.0). It was implemented during the OGC Web Services Testbed, Phase 9 (OWS-9) and tested to be compliant to this specification within the OGC CITE testing in December of 2012.

This project follows the Gitflow branching model. "master" reflects the latest stable release. Ongoing development is done in branch develop and dedicated feature branches (feature-*).

Code Compilation

This project is managed with Maven. Simply run mvn clean install to create a deployable .JAR file.
